Problems solved by technology

[0002] In the era of information explosion, a large amount of information and data are generated every day. It is a routine business to store, search, update, and delete massive amounts of data by using SQL statements. However, when executing certain SQL statements, it often takes a long time and Low operating efficiency, which seriously hinders the operating speed of the system, prolongs the page response speed, affects system performance, and thus affects user experience

Abstract

The invention provides a SQL (structured query language) sentence processing method and device. The method includes following steps: distributing SQL sentences into corresponding queues according to acquired SQL sentences whose execution time is longer than or equal to a first preset value within a preset time period and execution time number of the SQL sentences; acquiring average execution time of the SQL sentences in each queue; processing selected SQL sentences whose average execution time is longer than or equal to a second preset value and / or the execution time number is larger than or equal to a third preset value. In the technical scheme, the SQL sentences with large execution time number and serious time consumption are optimized after the SQL sentences with the average execution time longer than or equal to the second preset value and / or the execution time number is larger than or equal to the third preset value are found out, so that system running efficiency is greatly improved, and user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of cloud computing, and in particular relates to a SQL statement processing method and device. Background technique [0002] In the era of information explosion, a large amount of information and data are generated every day. It is a routine business to store, search, update, and delete massive amounts of data by using SQL statements. However, when executing certain SQL statements, it often takes a long time and In the case of low operating efficiency, this seriously hinders the operating speed of the system, prolongs the page response speed, affects system performance, and thus affects user experience. [0003] Therefore, it is urgent to provide a SQL statement processing solution to solve the above technical problems. Contents of the invention [0004] The present invention provides a SQL statement processing method and device to solve the above problems. [0005] An embodiment of the present invention...
